CONSTANTIN LAZAREVITOH, OF BROOKLYN, NEW YORK, A'SSIGNOR TO HIMSELF AND JOHN C. LAZABEVITOH, OFSAME PLACER FIRE-LADDER.

SPECIFICATION forming part of Letters Patent No. 316,155, dated April 21, 1885.

Application liled March 16, 1885. (No model.) 7

To all whom it may concern:

Be it known that l, CONsTANTIN-LAZARE- VITOH, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Fire-Ladder, of which the following is a full, clear, and exact description.

This invention relates to an extension fireladder attached to a truck, the sections of and parts connected to the ladder being adapted to be folded together to lie flat upon the truck, and the invention consists, principally, of a folding brace or support attached to the ladder and truck arranged for bracing the ladder directly from the ground when the sections of the ladder are elevated for use.

The invention also consists in providing the sections of the ladder With permanent waterpipes for adapting the ladder when elevated to be used also as awater-tower.

The invention also consists of the means employed for elevating the ladder, and of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Referenceis to be had to the accompanying drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my new fireladder as it appears when elevated and wholly extended, and the water-pipes of the upper and lower sections coupled together. Fig. 2 is a front elevation of the same, the upper section of the ladder not being elevated. Fig. 3 is a side elevation of the truck and ladder folded to. lie flat upon the truck. Fig. 4 is a sectional elevation of the same, the'wheels and axles of the truck being omitted. Fig. 5 is a side elevation of the truck and ladder partially raised, ready to be turned to the position shown in Fig. 1, for lowering the folding sectional brace C to the ground. Fig. 6 is a plan View of the truck and brace O, placed flat upon the truck, the other portions of the ladder being removed; and Fig. 7 is a detailed rear elevation of the upper portion of the ladder, showingthe arrangement of cords for operating the water-nozzle from the ground.

A-represents a' four-wheeled truck, with a frame composed of the side pieces, a a, end pieces, aa, and intermediate cross-pieces, a

a The side pieces, a, have the upwardlyprojecting flanges a formedupon or secured to them for the purposes here nafterdescribed.

Upon the forward end of the frameof the truck is placed the turn-table B. To this is secured, by the hinge b, the folding sectional support or brace O, which is composed of the upper section, 0, and lower section, 0*,which latter is adapted to rest upon the ground at its lower end to support and brace the ladder when elevated, as illustrated in Fig. l. The section 0 of the hingedand' folding brace or support 0 is provided, near the hinge b, with the heavy plates 6 c, to which the lower end of the lower section,.D, of the ladder is at tached by the heavy rod 0.

Attached to the lower section, D, of the ladder, near its upper end, are the brace-rods d, provided at their lower ends with the hooks d or other attachments, adapting the rods (2 to be fastened to the ends of the adjustable cross-piece E, placed upon the section 0 of the folding brace O. The cross-piece E is held to the section (3 by plates or flanges a, running in grooves e, and the cross-piece E is provided with pawls 6 adapted to engage with the ratchet-plates e of the section 0 so that the crosspiece E may be held at any desired position upon the section 0 The objects of the rods d and adjustable cross-piece E are, first,to brace the ladder from the section 0 of the folding brace G, which section rests directly upon the ground, and secondly, to enable the pitch of the ladder to be varied when elevated as circumstances require.

The pawls c are held in contaet with the ratchet-plates e by the action of a spring, 6, Figs. 4c and 6, placed on a rod, 0 to which the pawls are attached, and said rod is provided with arm 6", to which the cord e -is attached,

the endless cord or chain f that passes over the Windlass f and pulley f as shown in Fig.

4, so that by turning the Windlass f the cross-' tion D of the ladder, as shown in the other figures of the drawings.

For raising and lowering the section F, I provide the section D at its lower end with the Windlass h, and at its upper end with the pulley h, and attach to the lower rung, h ,Fig. 4', of th'e'section F the endless rope or chain'h that passes over pulley h and Windlass h, so that when the Windlass is revolved the chain or rope h will raise or lower the's'ection F; and I provide the Windlass h with pawl and ratchet h, Figs. 1, 2, 3, for holding the'section' F at any desired position. The'section F, when'elevated, will be'braced fr'orntheupper endof' section D, as shownin' Fig. 1, by the brace-pieces i iz' and said section F-is pro vided withthe permanent pipes F F ,that are adapted, when the section F is elevated; to be coupled to the permanent pipes F F attached to the lower section, D, so that'by coupling the hose of a fire-engineto the lower ends of the lower pipesF water may beforc'ed to the top of the ladder and discharged from'the noz'z'l'e F, with which the pipes F areconnected' by the branch pipes F F", as shown clearly in Fig. 2. The brace-rods 11 are'pivoted'to the section F of the laddernear its up"- perend,the rodst" are pivoted'to'thelower ends oftherods e, and are adapted to beat taehed to pins i at the sides of'thesection' F, and the rods 1' are also pivoted to the lower ends of the rods 6, and are adapted to: be at tachedto the pins 6* at the upper endsof the ladder-section- D, so that the rods together form tru's's braces, which may be easily con} nectedto-and disconnected from thesectioiisof the ladder and folded alongside'of the'section F of the ladder, so asnot to interfere with' the raising andloweringof the ladder. In

raising and lowering the section" F, the side plates,jj, and cross rod j act as keeper's and guides to the section F, and revent lateral displacement of the section F.

WVhenthe ladder isfolded down upon the truc'k-A,the sectional folding br'ace oi s'upport' O and sections D F of theladder willoccupy' nearly ahorizontal position uponthe frame of the truck, the brace or support 0 being at the bottom ,where it w'illbe held from lateral In elevating the ladder the first act'is to' break the general alignment of' the brace or" support 0 and the sections of the ladder. This I accomplish by the lifter G, pivoted between the side pieces, a a, of the frame of the truck, and adapted to be turned from the position shown in Fig. 4 (the position itwill occupy when the ladder is folded upon the truck) to that shown in Fig.5. The lifter G may be operated by hand or by the Windlass h, Fig. 4, pulley h, and rope attached to the Windlass, passed over the pulley 7c, and carried back and attached to the arms or levers k of the lifter, so that by turning the Windlass h to wind up the rope k the lever 70 will be drawn backward and the lifter turned upward upon its pivots, which will cause the cross-pieces k of the lifter to impinge upon the lower edges of the brace or support 0 and lift it so that it .will occupy the position shownin dotted lines in Fig; 5; When in this position,to lift the ladderto the position shown in fnllllin'es' in Fig. 5 the windlas'ses J 'Kshou'ld be simultaneouslyrevolved; which will act, respectively, to'wind up the ropes'L L andM, the former of which pass over pulleys L L and are attached to the upper end of the section 0 of the'brace or support 0, whilethe latter is attached directly to the rear or lower end of the section 0 of saidbra'ceor support. The windingup' of theropes L M will draw the brace o'rsupportG forwar'dand'turn'it on the hinge b and lift th'e'ladd'er. Shortly before the sections of the'lad'cle'r a'n'd sectional brace G reach t-hepositienshown i'nffull lines in Fig. 5 the notched end of the brace N, Fig. 4, should be placed upoiithe'crosspiecen of the section 0 of thebra'ce O, to prevent the ladder from being pitchedf' forward and to prevent the sections 0 (3 from being folded'too far. The brace N being put in" place; by turning the-windlass'J still farther" the whole'l'adder andfolding brace 0 maybe turned on hinge b, so als" t'o"lift the letter end of the'section 0 up fromtheiside'piece's, a, ofthe frame of'the truck, in which position the'turn-table B will begiveh acne-quarter revolution, which will i turn the ladder and swihg thesu'pp'ort C to one side of the frame ofthe truck. The pawl :z of windla'ss J'will be lifted rrqm'ratchet z and thewi'ndlass let back, whic'li'will' permit the ladder and support otolower until the lower end of section'G of thesupp'ort O rests uponthe ground, as shown in Fig; 1'. The braces cl'will now be attached to the adjii'stable cr'oss piece" E, and this cross-piece will then beelevated, as above described, for-"in- Thisdone,

turning windlass h, and the brace 13 t" 2' adjusted, and the water-pipes F F coupled together, when the ladder is ready for use both' as a fire-ladder and water-tower.

To fold the ladder, thereverse of the operationsfabovedetailed will be followed; p The nozzle]? is flexible, and its outer eiid" may be raised, lowered, or turned to the right or left for directing the jet of water either by hand by a person on the ladder, or it may be operated from the ground by the ropes O 0, both attached to the nozzle and both passed through the eye m, the rope 0 being first passed through the eye m at the opposite side of the ladder, as shown in Fig. 7. For raising and lowering the nozzle I use the windlass P, located at the lower end of the section 0 of the folding brace or support 0, around which windlass both ropes O 0 pass, so that both may be wound up to lower the nozzle, or both released to permit it to be raised by hand or by its own elasticity. To turn the nozzle to the right, both ropes O 0 should be released by the windlass P and rope O pulled downward, and to turn it to the left the rope 0 should be pulled downward.

When the ladder is folded and placed upon the truck, the ropes O 0 will be wound upon the windlass I, as will be understood from Figs. 3 and 4.

The braces d are each made of two parts telescoped together, as shown clearly in Figs. 3 and 5, and when the ladder is folded they are adapted to be held alongside the lower section, D, of the ladder by the hooks (1 as shown clearly in said figures.
